摘　　要：截割滚筒齿座在使用过程中出现断裂,利用金相显微镜对损坏组织进行检测。结果表明,齿座基体组织符合设计要求。对其断裂位置和形状进行分析,通过模拟其使用工况,分析齿座受力情况,判断为齿套锥度与齿座锥度不匹配,在周期性冲击载荷作用下,最终导致齿座断裂。The tooth seat of the cutting drum was broken in the process of use,and the damaged tissue was detected by metallographic microscope.The results showed that the matrix structure of the tooth seat met the design requirements.The fracture position and shape were analyzed,and the force of the tooth seat was analyzed by simulating its working condition.It was judged that the taper of the tooth sleeve did not match the taper of the tooth seat.Under the action of periodic impact load,the tooth seat eventually broke.

关 键 词：齿座 断裂 锥度
